Let me tell you a little something about myself: I am very critical of my own performances. I am always looking for ways to improve my material. Even if it's something as simple as a cosmetic change on a prop or a look or gesture.
As I have mentioned in the past, the secret to being a better performer is to give a damn. If you care you'll work on something until you are content with it. An act or performance can never be done. There is always something to improve.
The question is how do you find those improvements? Simple. Go out and effin' perform!! The more you sail the boat, the more leaks you will find. The more arrows you fire the better your aim will be. The more cats you shave the umm... furrier your.. uh.. pants will get.... (They can't all be gold).
My point is every performance is a learning experience IF YOU LET IT. Some people just perform, collect their check, and go home. Every time you perform something is different. Something is better or worse. Something can be fixed. You have to pay attention to it tho' You must be like skynet and become self-aware! Don't be too lazy either. Be proactive! (I don't mean the acne medication either) If you can't get to it right away, make a note of it. Every cell phone has a way to make notes. Take advantage of that!
The more you perform, the more chances you have to fix things. The more you fix, the better your act will get. The better your act is the happier you (and everyone who watches you) will be. So the next time you see me perform just know that afterward backstage I will be taking stock of everything that just occurred...
and possibly crying.
